Some years ago I bought 2 57 300-C doors, complete, better yet they
were both power window doors.

Cleaned them up, were in storage since early 60's, tried to test with a
little 12V battery I used to carry to junkyards for quicky testing.

That 12V battery was NOT enough to try and test a single power window
of that vintage. Service manual said the electric motor ran between 13
and 15 amps just to operate. I think Chrysler used the same motors for
many years.
